Proposal for introduction 3D object registration into the Polish legal framework

The aim of this article is to answer the question whether it is justified to introduce the registration of 3D objects in the real estate cadastre in Poland, considering the scope of information registered in other countries. This aim requires the discussion of new legal and technical conditions that might be necessary to introduce the registration of 3D objects in the real estate cadastre in the light of the new proposed legal regulations in Poland. The article presents the principles of functioning of the multidimensional cadastre in various countries. The research method includes both the analysis of literature on the registration of cadastral objects and the planned legal regulations. The research focused on the analysis of the scope of information and the method of registering objects in the real estate cadastre in Poland. The article presents a proposal to amend the geodetic legal and technical regulations concerning both objective and subjective data registered in the real estate cadastre and documents that form the basis for entries in the real estate cadastre. It takes into account the draft of the Layered Development Act, implemented in 2021–2022 at the De Republica Institute. The authors propose changes to the provisions in the existing legal regulations, which would enable the collection, processing, updating and sharing of information on 3D objects and their owners and other entities with the right to dispose of a separate space above or below the ground surface. In order to register 3D objects together with the right to them in accordance with the provisions of the draft Act, the authors recommend introducing the following entity: Zabudowca in EGB_StatusPodmiotuEwid, as well as a document used to disclose the scope of the 3D object, i.e. the decision to establish the right to develop in EGB_RodzajDokumentu.
